The Nearest Neutron Star Candidate in a Binary Revealed by Optical Time-domain Surveys
Ling-Lin Zheng, Mouyuan Sun, Wei-Min Gu +19
The near-Earth (within pc) supernova explosions in the past several million years can cause the global deposition of radioactive elements (e.g., Fe) on Earth. The…
A White Dwarf-Main Sequence Binary Unveiled by Time-Domain Observations from LAMOST and TESS
Ling-Lin Zheng, Wei-Min Gu, Mouyuan Sun +16
We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
A long-period pre-ELM system discovered from LAMOST medium-resolution survey
Zhi-Xiang Zhang, Ling-Lin Zheng, Wei-Min Gu +16
We present LAMOST~J041920.07+072545.4 (hereafter J0419), a close binary consisting of a bloated extremely low mass pre-white dwarf (pre-ELM WD) and a compact object with an orbital…
A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
Repeating Ultraluminous X-ray Bursts and Repeating Fast Radio Bursts: A Possible Association?
Hao-Yan Chen, Wei-Min Gu, Jin-Bo Fu +3
Ultraluminous X-ray bursts (hereafter ULXBs) are ultraluminous X-ray flares with a fast rise ( one minute) and a slow decay ( an hour), which are commonly observed in e…
Searching for compact objects in binaries with Gaia DR3
Jin-Bo Fu, Wei-Min Gu, Zhi-Xiang Zhang +4
We search for compact objects in binaries based on Gaia DR3. A sample of ten targets is derived under the conditions: radial velocity variable, low temperature ($T_{\rm eff} < 6000…
Searching for Black Hole Candidates by LAMOST and ASAS-SN
Ling-Lin Zheng, Wei-Min Gu, Tuan Yi +13
Most dynamically confirmed stellar-mass black holes and the candidates were originally selected from X-ray outbursts. In the present work, we search for black hole candidates in th…
A Method to Search for Black Hole Candidates with Giant Companions by LAMOST
Wei-Min Gu, Hui-Jun Mu, Jin-Bo Fu +10
We propose a method to search for stellar-mass black hole (BH) candidates with giant companions from spectroscopic observations. Based on the stellar spectra of LAMOST Data Release…
